Abstract:
Pratt, Adam, and Fischer (2007) investigated the effect of surrounding targets on the time it took to move to an individual target and found that the movement time to a central target was above the Fitts's law line related to the first and last targets. They explained their results in terms of a "visuomotor hypothesis." Here, an alternative explanation is given in terms of a previously validated model of the "available target width" that is determined by the size of the target and the width of the finger pad that is being used to hit the target.
